MECHANICAL MOVEMENT.

SPECIFIGATIONfOrming part of Letters Patent No. 759,423, dated May 10, 1904.

Application filed June 9, 1902. Serial No. 110,779. (No model.)

T0 (ZZZ whom it may concern.-

Be it known that we, CONRAD DIETZ and JOHN DIETZ, citizens of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification.

Our invention relates to improvements in compound mechanical movements.

The object of our invention is to provide means for producing simultaneously alternating, rotary, and longitudinal movements.

The novelty of our invention will be hereinafter more fully set forth, and specifically pointed out in the claims.

In the drawings which serve to illustrate our invention, Figure 1 is a side elevation of the frame, male spiral and stem, and operative mechanism. Fig. 2 is a top plan view of the same with portion of the crank-wheel broken away. Fig. 3 is a view on the line 00 w, Fig. 1, looking in the direction of the arrow and showing the frame and female spiral in section, the male spiral in side elevation, and the cam or yoke in front elevation. Fig. 4 is a transverse section of Fig. 3, taken on the line y y of said Fig. 3. Fig. 5 is a section taken on the line 2 .2, Fig. 1, looking in the direction of the arrow, showing the frame and a portion of the fly or hand wheel.

We prefer to construct our improved device substantially'as follows: The frame or housing is formed with a fiat base 1, having thereth rough a journal-bearing provided with a female spiral 2 and having mounted thereon a standard 3, provided with a journal-bearing 4: to receive the stem 5, carrying the male spiral 6, which is adapted to take intoand traverse said female spiral. is also provided with bearings 7 and 8 to receive and support the crank-shaft 9, carrying cog-wheel 10, which engages and is adapted to actuate disk 11, which disk is mounted and adapted to rotate on stud 12. The disk 11 is provided with pin 13, carrying roller 14, having shoulder 15, said roller being adapted to engage the walls of guideway on cam or yoke 16, which is pivotally connected by The standard 3 bearings 17 taking over said stem and held from endwise movement thereon by collar 18, rigidly secured thereto and fitting between said bearings 17. The cam or yoke 16 is provided with a recess 19 to receive the shoulder 15. of the roller for the purpose of holding the latter from disengagement therewith. VVe preferably provide braces 20 to strengthen the-cam or yoke. I

When the frame is mounted horizontally with the male spiral in vertical position, the cam or yoke is pivotally connected thereto, with guideway 21 disposed at right angles to the male spiral stem, so that as the fly-wheel 22 is turned and the disk carrying crank-pin revolved the roller on the crank-pin will rotate back and forth from one end to the other of said guideway, thus imparting from the crank through the cam or yoke to the male spiral stem an alternating longitudinal movement, While at the same time the fem ale spiral guides the male spiral stem in rotary direction. When the male spiral stem is up, the cam or yoke will be in the position shown by heavy lines, Fig. 1. 'When said stem has traveled lengthwise one full stroke, the cam or yoke will be in the position shown by dotted lines, Fig. 1. When it has traveled one-half of a stroke or the disk made one-fourth of a revolution, the cam or yoke will be in the position shown by heavy lines, Fig. 3, the roller having reached the end of the guideway, ready, as the disk revolves, to travel back to the other end thereof, and so on. The dotted lines in Fig. 3 show the position of the cam or yoke and roller when the parts are in the position shown by heavy lines, Fig. 1. It will be noted that when the crank-pin and yoke are at the highest point the roller is in the center of the cam or yoke, as shown by dotted lines, Fig. 3, and when the disk has traveled one-fourth of a revolution the roller will be at the position shown by heavy lines, Fig. 3. When the disk has traveled one-half of a revolution, the cam or yoke will be at the position shown by dotted lines, Fig. 1, and the male spiral stem will have traveled its full length longitudinally in one direction. When the revolution of the disk is completed, it will have reversed and traveled back the full length of the stroke. It will be observed that the reversal of movement of the male spiral and stem takes place without reversing the direction of movement of the fly-wheel or crank and that the crank may be moved in either direction to actuate said male spiral and stem. An important advantage derived by our construction is that the reversal of movement takes place without producing any jarring effect or making any noise. The length of movement of the male spiral stem is determined by the size of crank stroke and length of guideway in cam or yoke traversed by the crank-pin or roller.

hile our invention is especially adapted for use in machines for washing clothing and in churns for producing agitation, it may also be used for such other purposes as will require the compound movements which it is adapted to produce.

The advantages of the movements secured by our device in washing clothing are that it rotates and queezes them and dashes them through the Water, producing a good rinsing effect by compressing the clothing together and then pulling them apart, so as to allow the dirt to be freed in the water. It also produces a suction by pushing the clothing through the water in its downward movement and creates a vacuum having a drawing effect which tends to draw the water through the clothing and rinse the dirt therefrom.

When our device is applied for use in a churn, we are enabled to produce a thorough agitation by means of the alternating or reversible rotary movement and the simultaneous alternating or reversible lengthwise movement, or, if desired, the rotary movement may be omitted by dispensing with the spirals.

It will be obvious from the above description that our device is very simple in construction and operation and easily adapted for application to various styles of machines. It will also be obvious that our device is capable of considerable modification without material departure from the scope and spirit of the invention, which is to produce the compound movements above referred to, and for this reason we do not wish to be understood as limiting ourselves to the precise form or arrangement of the parts herein set forth.

We claim-- 1. In mechanical movements, a frame, a female spiral disposed vertically therein, a male spiral, journaled in said frame and adapted to take into and engage said female spiral, a cam or yoke pivotally mounted on and carried by said male spiral independent of the frame and having a horizontal guideway, a crank adapted to engage said guideway to move and travel back and forth therein to drive said male spiral first in one direction and then in the reverse direction within said female spiral.

2. In mechanical movements, a frame, a female spiral disposed vertically therein, a male spiral journaled vertically in said frame and adapted to take into and engage said female spiral, a cam or yoke pivotally mounted on and carried by said male spiral independent of the frame and having a guideway, a crank and a roller upon the pin thereof, adapted to engage and traverse said guideway.

3. In mechanical movements, a female spiral, a male spiral adapted to take into said female spiral, cam or yoke loosely mounted on said male spiral and having a recessed guideway. a crank and a roller having a flange adapted to engage the walls of said recess, said roller being loosely mounted on said crank, substantially as and for the purposes set forth,

4. In mechanical movements, a frame, a female spiral disposed vertically therein, a male spiral journaled vertically in said frame and adapted to traverse said female spiral, a yoke pivotally mounted upon said male spiral independent of the frame and having a transverse guideway therein, a crank-wheel adapted to engage the face of said yoke and having a pin adapted to traverse said guideway.

5. In mechanical movements, a frame, a female spiral disposed vertically therein, a male spiral journaled vertically in said frame and adapted to take into and engage said female spiral, a cam or yoke pivotally mounted on and carried by said male spiral and having a guideway, a crank adapted to traverse said guideway, a gear upon said crank and a pinion adapted to mesh therewith and drive said crank.
